8.1.1.1
Condenser (only refrigerated centrifuges with an air-cooled refrigeration system)
In order to cool the refrigerant that is compressed by the refrigeration unit,
centrifuges with an air-cooled refrigeration system use a lamellar
condenser. It is cooled by air.
Dust and dirt obstruct the cooling flow of air. The dust on condenser pipes
and lamellas reduces the heat exchange and thus the performance of the
refrigeration unit.
This is why the installation site should be as clean as possible.
• Check the condenser at least once a month for dirt and clean it if
necessary.
• If you have any queries, please contact service (see chapter 7.3 -

Accessories
CAUTION
For the care of the accessories, special safety measures must be
considered as these are measures that will ensure operational safety at
the same time!
• Immediately rinse off the rotor, buckets, or accessories under running
water if they have come into contact with any liquids that may cause
corrosion. Use a brush for test tubes in order to clean the bores of angle
rotors. Turn the rotor upside down and allow it to dry completely.
• Clean the accessories outside the centrifuge once a week or preferably
after each use. Adapters should be removed, cleaned and dried.
CAUTION
Do not clean the accessories in a dishwasher!
Cleaning in a dishwasher removes the anodised coating; the result is
cracking in areas that are subject to stress.
• If the rotors or accessories have been contaminated with toxic,
radioactive, or pathogenic substances, clean them immediately with a
suitable decontamination agent (depending on the type of
contamination).
Take suitable precautions for your own safety if there is
a risk of toxic, radioactive, or pathogenic contamination.
• Dry the accessories with a soft cloth or in a drying chamber at
approx. 50°C.
